Is Fluoride in Water Really Safe? Study Raises Serious Health Concerns

United States: Recent reports about potential health risks and whether fluoride benefits are as big as once believed have prompted scrutiny of a public health practice – adding fluoride to water supplies. 

This is because, as with some questions, the safety of the practice and new data raise questions about the value of fluoride.

Adding fluoride to tap water produces only a slight benefit in reducing tooth decay in children’s baby teeth, a new report from the Cochrane Collaboration, an independent group reviewing scientific research, finds. 

It is found that adding fluoride to tap water is a slight benefit, leading to slightly fewer cavities in children’s baby teeth, CNN Health reported. 

More about the finding 

Research done before 1975 had large benefits; children living in areas with fluoride added to their water averaged about one fewer primary teeth affected by decay than those of children living in areas without water fluoridation. 

Those findings don’t apply to more current populations with increased access to other sources of fluoride and lower levels of dental disease at baseline. 

Since the 1970s, fluoride-containing toothpaste has been widely available and is more often used. 

According to the new report published this week, fluoride in water was tied to a difference in decay of only about a quarter of a tooth, on average, in more recent studies. 

The federal judge, last month had asked the US Environmental Agency to further regulate fluoride in drinking water in response to concerns that fluoride may affect young children’s intellectual development, CNN Health reported. 

In light of concerns about fluoride’s possible effect on young children’s intellectual development, a federal judge last month ordered that the EPA further regulate fluoride in drinking water. 

Some foods and groundwater have fluoride, a mineral. It can help protect tooth enamel, which can erode with acids produced by plaque, bacteria, sugar, and other acids found in your mouth. 

The USA began adding fluoride to public water systems in 1945. 

Now, almost three-quarters of the US population, about two hundred and nine million people, are served by drinking water systems that have been fluoridated, according to data from the CDC.
